This Tesla-Supplying Battery Maker Has Lost Some of Its Power

The world’s largest maker of EV batteries is struggling to win again investor confidence after shedding practically $100 billion of market worth in lower than six months.

The market has cooled on China’s Contemporary Amperex Technology Co. , or CATL, as excessive raw-material prices have squeezed its revenue margins. Over a long term, some traders and analysts query whether or not CATL’s development may endure as rivals increase quickly and clients attempt to diversify their provide chains.
